Package for stick-like article

ABSTRACT

A package for a stick-like article includes a first film having flat portions (14b) and a bulging portion (14a) for enclosing a stick-like article, and a second film which is joined to the first film by heat sealing. Joint portions (33, 34) are formed near both longitudinal ends. Since the package is separated from a packaging container (11) except for areas near both longitudinal ends, fingers can be easily inserted between the package for a stick-like article and the packaging container (11). This makes it easy to remove the package for a stick-like article from the packaging container (11). Since the width of the flat portions (14b) at the lateral edges of the package for a stick-like article can be made narrower, the width of the package becomes narrower. Accordingly, the consumption of the first and second films can be reduced. When perforations (36, 37) are formed at locations which are offset from the joint portions (33, 34) toward the center of the package, the perforations (36, 37) act as breaking lines. Accordingly, the package for a stick-like article can be easily removed from the packaging container (11).

TECHNICAL FIELD

The present invention relates to a package for a stick-like article.

BACKGROUND ART

Conventionally, liquid foods such as milk and soft drinks are containedand sold in a packaging container made of a packaging material which isfabricated by coating the inner and outer surfaces of a paper substratewith a polyethylene resin or the like.

Examples of such a packaging container include a gable-top typepackaging container having a sloped top, and a brick-type packagingcontainer having a flat top. Liquid food contained in a packagingcontainer which has a small capacity such that a purchaser can consumethe food at one time is generally sold at a store or by an automaticvending machine, and is frequently consumed at the place where the foodis purchased. Accordingly, a film package containing a straw is usuallyadhered to each packaging container for sale.

Also, in the sale of semi-hard foods such as yogurt and frozen desertscontained in packaging containers, a film package containing a spoonmade of a resin is usually adhered to each packaging container.

FIG. 1 is a perspective view of a conventional packaging container, andFIG. 2 is a perspective view of a conventional straw package.

As shown in these drawings, a package for a stick-like article, forexample, a straw package 55 is adhered to a side surface of a packagingcontainer 11. A purchaser of a food placed in the packaging container 11removes the straw package 55 from the packaging container 11, and takesout a straw 56 from the straw package 55. The straw package 55 iscomposed of a first film 14 and a second film 13 which are joinedtogether at their peripheral edges by heat sealing. The first film 14has a bulging portion 14a and flat portions 14b. The second film 13 isjoined to the first film 14 by heat sealing to enclose the straw 56 inthe bulging portion 14a in a sealed manner.

A plurality of straw packages 55 are first manufactured as anunillustrated straw ladder. Each straw package 55 cut away from thestraw ladder is pressed against the packaging container 11 and isadhered thereto by heat fusion. Numeral 57 denotes joint portions atwhich the straw package 55 is adhered to the packaging container 11.

Next, a conventional straw applicator will be described.

FIG. 3 is an enlarged view showing a heat-fusing section of aconventional straw applicator.

In FIG. 3, numeral 55 denotes a straw package which has been cut from anunillustrated straw ladder, and numeral 56 denotes a straw enclosed inthe straw package 55. Numeral 61 denotes a heating section while numeral62a denotes a depression which is formed in the forward end (theleft-hand end in FIG. 3) of the heating section 61 at its center so asto allow a bulging portion 14a to enter there.

The heating section 61 holds the straw package 55 while receiving thebulging portion 14a in the depression 62a, and adheres the straw package55 to the packaging container 11 (FIG. 1). To this end, two pairs ofheaters 63 are provided at positions corresponding to the flat portions14b (one pair of heaters is shown in FIG. 3).

The conventional package for a stick-like article, however, has thedrawback that it is difficult to insert the fingers between the strawpackage 55 and the packaging container 11, because the straw package 55is affixed to the packaging container 11 by pressing the flat portions14b against the packaging container 11 using the two pairs of heaters63. This makes it difficult to remove the straw package 55 from thepackaging container 11.

In addition, when the straw package 55 is adhered to the packagingcontainer 11, in order to prevent the straw 56 from deforming orchemically transforming due to heat, the width of the flat portions 14bmust be large enough to prevent the heat of the heaters 63 from reachingthe straw 56. Therefore, the width of the straw package 55 becomeslarge, resulting in an increase in the consumption of the first andsecond films 14 and 13, and increasing costs.

Similar problems occur when an unillustrated spoon package is adhered tothe packaging container 11 in the above-described manner. That is, itbecomes difficult to remove the spoon package from the packagingcontainer 11. Also, since the width of the spoon package becomes large,the amount of film required increases, leading to an increase in costs.

An object of the present invention is to solve the above-describedproblems of conventional packages for stick-like articles, and toprovide a package for a stick-like article which is easily removed froma packaging container, which requires a reduced amount of film, andwhich reduces costs.

DISCLOSURE OF THE INVENTION

To achieve the objects, a package for a stick-like article according tothe present invention includes a first film formed with flat portionsand a bulging portion for enclosing a stick-like article, and a secondfilm which is joined to the first film by heat sealing.

Joint portions are formed near both longitudinal ends of the package.

In this case, the first and second films are joined to the packagingcontainer only through the joint portions. Accordingly, the package fora stick-like article is separated from the packaging container exceptfor areas near both longitudinal ends, which allows a purchaser toinsert his or her fingers between the package for a stick-like articleand the packaging container. This makes it easy to remove the packagefor a stick-like article from the packaging container.

Moreover, since the joint portions are formed near both longitudinalends of the package for a stick-like article, the width of the flatportions of the package located at the lateral edges can be madenarrower. Accordingly, the width of the package becomes narrower, whichreduces the consumption of the first and second films, leading to areduction in costs.

In another package for a stick-like article according to the presentinvention, perforations are formed at locations which are offset fromthe joint portions toward the center of the package and which areslightly offset from the boundaries between the bulging portion and theflat portions toward the longitudinal ends of the package.

In this case, the perforations act as breaking lines when the packagefor a stick-like article is removed from the packaging container.Accordingly, the package for a stick-like article can be easily removedfrom the packaging container.

In still another package for a stick-like article according to thepresent invention, the second film is joined to the packaging containerat the joint portions by heat fusion. In this case, a heater is pressedagainst the joint portions.

In still another package for a stick-like article according to thepresent invention, the second film is joined to the packaging containerat the joint portions using an adhesive material. For example, hot meltis sprayed on the packaging container, and the package for a stick-likearticle is pressed against the packaging container via the hot melt.

Still another package for a stick-like article according to the presentinvention includes a first film formed with flat portions and a bulgingportion for enclosing a stick-like article, and a second film which isjoined to the first film by heat sealing.

The second film contains, as a base resin, an ethylene-vinyl acetatecopolymer having a melting point and a vicat softening point both higherthan those of the hot melt.

Accordingly, even though the surface of the packaging container and thefirst film are made of resins having different melting points, the resinforming the surface of the packaging container and the resin of thesecond film, which are present at the joint portions, are melted andjoined together when a heater is pressed against the joint portions. Asa result, the straw package can be securely adhered to the packagingcontainer.

Also, the second film does not present stickiness at an ordinarytemperature. Moreover, even when a ladder of a plurality of packages fora stick-like article is rolled up, the ladder does not adhere to eachother.

Since the ethylene-vinyl acetate copolymer is used only for the secondfilm, the consumption of the ethylene-vinyl acetate copolymer can bereduced, leading to reduced costs.

Even when the packaging container is stored in an automatic vendingmachine at a temperature of 50° C. or higher, or at a temperature of 10°C. or lower, the package for a stick-like article does not peel off fromthe packaging container.

Still another package for a stick-like article according to the presentinvention includes a first film formed with flat portions and a bulgingportion for enclosing a stick-like article, a second film which isjoined to the first film by heat sealing, and an adhesive film whichcovers the second film to form joint portions.

In this case, the package for a stick-like article is adhered to thepackaging container by heat fusion at joint portions formed near bothlongitudinal ends of the package. Since the second film is joined to thepackaging container by heat fusion only through the joint portions, thepackage for a stick-like article is separated from the packagingcontainer except for areas near both longitudinal ends, which allows apurchaser to insert his or her fingers between the package for astick-like article and the packaging container. This makes it easy toremove the package for a stick-like article from the packagingcontainer.

The adhesive film contains, as a base resin, an ethylene-vinyl acetatecopolymer having a melting point and a vicat softening point both higherthan those of the hot melt.

Accordingly, even though the surface of the packaging container and thesecond film are made of resins having different melting points, theresin forming the surface of the packaging container and the resin ofthe adhesive film, which are present at the joint portions, are meltedand joined together when a heater is pressed against the joint portions.

As a result, the straw package can be securely adhered to the packagingcontainer.

Also, the adhesive film does not present stickiness at an ordinarytemperature. Moreover, even when a ladder of a plurality of packages fora stick-like article is rolled up, the ladder does not adhere to eachother.

Since the ethylene-vinyl acetate copolymer is used only for the adhesivefilm, the consumption of the ethylene-vinyl acetate copolymer can bereduced, leading to reduced costs.

Even when the packaging container is stored in an automatic vendingmachine at a temperature of 50° C. or higher, or at a temperature of 10°C. or lower, the package for a stick-like article does not peel off fromthe packaging container.

BEST MODE FOR CARRYING OUT THE INVENTION

Embodiments of the present invention will now be described in detailwith reference to the drawings. Although a straw package will bedescribed as an example of a package for a stick-like article, thepresent invention can be applied to spoon packages.

FIG. 4 is a view showing a state in which a straw package according to afirst embodiment of the present invention is adhered to a packagingcontainer, FIG. 5 is a longitudinal cross section of the straw packageaccording to the first embodiment of the present invention, and FIG. 6is a lateral cross section of the straw package according to the firstembodiment of the present invention.

As shown in these drawings, a straw package 31 is adhered to a sidesurface of a packaging container 11. To adhere the long straw package 31within a limited area, the straw package 31 is disposed along a diagonalline of the side surface of the packaging container 11.

The straw package 31 is composed of a first film 14 and a second film 13which are joined together at their peripheral edges by heat sealing. Thefirst film 14 has a bulging portion 14a and flat portions 14b. Thesecond film 13 is joined to the first film 14 by heat sealing to enclosea straw 56 in the bulging portion 14a in a sealed manner.

In the present embodiment, a plurality of bulging portions 14a areformed at predetermined intervals in the first film 14 having apredetermined width. Straws 56 are placed in the bulging portions 14a,and the second film 13 is superposed on the first film 14. The firstfilm 14 and the second film 13 are joined together at the flat portions14b by heat sealing, so that an unillustrated straw ladder is obtained.Subsequently, each straw package 31 is cut from the straw ladder,pressed against the packaging container 11, and joined thereto by heatfusion.

To this end, joint portions 33 and 34 are formed in the flat portions14b provided near both longitudinal ends of the straw package 31. Whenunillustrated heaters are pressed against the joint portions 33 and 34,the resin forming the joint portions 33 and 34 and the resin coated onthe surface of the packaging container are melted and joined together.

In this case, the second film 13 is joined to the packaging container 11only through the joint portions 33 and 34. Accordingly, as shown in FIG.5, the straw package 31 is separated from the packaging container 11except for areas near both longitudinal ends, which allows a purchaserto insert his or her fingers between the straw package 31 and thepackaging container 11. This makes it easy to remove the straw package31 from the packaging container 11.

Moreover, since the joint portions 33 and 34 are formed near bothlongitudinal ends of the straw package 31, the width of the flatportions 14b located at the lateral edges of the straw package 31 can bemade narrower. Accordingly, the width of the straw package 31 becomesnarrower, which reduces the consumption of the first and second films 14and 13, leading to a reduction in costs.

Perforations 36 and 37 are formed at locations which are offset from thejoint portions 33 and 34 toward the center of the straw package 31 andwhich are slightly offset from the boundaries between the bulgingportion 14a and the flat portions 14b toward the longitudinal ends ofthe package 31 such that the perforations 36 and 37 cross the strawpackage 31 in the lateral direction. The perforations 36 and 37 areformed by unillustrated needle-shaped heaters, while the first film 14and the second film 13 are heat-sealed together at predeterminedintervals. Since the perforations 36 and 37 are formed in the flatportions 14b at which the first and second films 14 and 13 have beensealed together by heat, the sealing performance of the straw package 31does not deteriorate due to the perforations 36 and 37.

The resin composing the first and second films 14 and 13 are melted andjoined together, due to heat of the needle-shaped heaters, at theperipheral edge of each hole of the perforations 36 and 37. Accordingly,even when the perforations 36 and 37 are formed at the boundariesbetween the bulging portion 14a and the flat portions 14b, the sealingperformance of the straw package 31 can be maintained.

As described above, the perforations 36 and 37 are formed at locationswhich are offset from the joint portions 33 and 34 toward the centralportion of the straw package 31, the perforations 36 and 37 act asbreaking lines when the straw package 31 is removed from the packagingcontainer 11. Accordingly, the straw package 31 can be easily removedfrom the packaging container 11.

Also, since the perforations 36 and 37 are formed at the boundariesbetween the bulging portion 14a and the flat portions 14b, or at thelocations which are slightly offset from the boundaries toward thelongitudinal ends of the package, the perforations 36 and 37 can be tornwith a weak force after removal of the straw package 31 from thepackaging container 11. Accordingly, the straw 56 can be easily takenout of the straw package 31.

The first and second films 14 and 13 are manufactured, for example, byan inflation technique using polyolefin resins such as polyethylene (PE)resins, high density polyethylene (HDPE) resins, low densitypolyethylene (LDPE) resins, polypropylene (PP) resins, and orientedpolypropylene (OPP) resins. When the surface of the packaging container11 is coated with a resin which is the same as or highly compatible withthe resin of the second film 13, the second film 13 can be effectivelyjoined to the packaging container 11 by heat fusion. Accordingly, whenthe heaters are pressed against the joint portions 33 and 34, thepolyolefin resin which is present at the joint portions 33 and 34 andthe resin coated on the surface of the packaging container 11 are meltedand joined together in order that the straw package 31 is adhered to thepackaging container 11. When the oriented polypropylene resin is used,polypropylene resin is extruded to obtain a film, which is thenstretched uniaxially or biaxially. In this case, the polypropylene resinbecomes transparent because it crystallizes while being formed into afilm.

In place of the polyolefin resin, a non-olefin resin may be used for thefirst and second films 14 and 13.

When the first and second films 14 and 13 are made of polypropyleneresin or the like and the surface of the packaging container 11 iscoated with polyethylene resin or the like, their compatibility becomeslow because their melting points differ considerably from each other.Therefore, it becomes difficult to join the second film 13 to thepackaging container 11 by heat fusion. In this case, even if the heatersare pressed against the joint portions 33 and 34, the polypropyleneresin which is present at the joint portions 33 and 34 is not joined byfusion to the polyethylene resin coated on the surface of the packagingcontainer 11.

To overcome this problem, when a non-olefin resin, a polypropyleneresin, or the like is used for the first and second films 14 and 13, anadhesive material may be disposed at the joint portions 33 and 34between the second film 13 and the polyethylene resin coated on thesurface of the packaging container 11. In this case, the straw package31 is adhered to the packaging container 11 via the adhesive material.Next, second and third embodiments of the present invention which employsuch a structure will be described.

FIG. 7 is a lateral cross section of a straw package according to thesecond embodiment of the present invention.

As shown in FIG. 7, a straw package 31 is composed of a first film 14and a second film 13, and encloses a straw 56 in a bulging portion 14a.A bonding agent 61 serving as an adhesive material is provided betweenthe second film 13 and the packaging container 11. The bonding agent 61is applied or sprayed with an unillustrated hot-melt gun.

A hot melt which contains an ethylene-vinyl acetate copolymer (EVA) as abase component, can be used as the bonding agent 61. In this case, thehot melt is sprayed from the hot-melt gun against the side wall of thepackaging material 11, and the straw package 31 is then pressed againstand adhered to the packaging container 11 via the hot melt.

When hot melt is used as the bonding agent 61, an unillustrated heatingdevice is necessary to maintain the hot melt in a molten state.

This increases the size of an unillustrated straw applicator and theenergy consumption thereof. Also, since the hot melt is always heated,its properties deteriorate, so that the bonding force decreases, and thenozzle of the hot-melt gun is stuffed.

Also, when the hot melt is sprayed from the hot-melt gun, the hot meltscatters. As a result, the consumption of the hot melt increases,thereby increasing costs. Also, the hot melt cannot be uniformly appliedon the surface of the packaging container 11, and so the straw package31 may peel off from the packaging container 11.

Moreover, when the packaging container 11 is stored in an automaticvending machine at a temperature of 50° C. or higher, the hot meltliquefies. When the packaging container is stored in an automaticvending machine at a temperature of 10° C. or lower, the hot meltsolidifies. In both cases, the straw package 31 may peel off from thepackaging container 11.

Next, a description is given of the third embodiment which has overcomethe above-described problem. In this embodiment, in place of the bondingagent 61, an adhesive film having a melting point and a vicat softeningpoint both higher than those of the hot melt is used as the adhesivematerial.

FIG. 8 is a rear elevation of a straw package according to the thirdembodiment of the present invention, FIG. 9 is a rear elevation of astraw ladder used in the third embodiment of the present invention, FIG.10 shows an apparatus for superposing an adhesive film used in the thirdembodiment of the present invention, and FIG. 11 is a chart showingproperties of ethylene-vinyl acetate copolymer used in the thirdembodiment of the present invention. In FIG. 11, the abscissa representsthe melting point, and the ordinate represents the vicat point.

As shown in FIG. 8, a straw package 31 is composed of a first film 14and a second film 13, and encloses a straw 56 in a bulging portion 14a(FIG. 4). Adhesive films 64 are previously superposed on the second film13 on the rear surface of the straw package 31 near both longitudinalends.

In actual cases, the straw package 31 having the above-describedstructure is formed as a straw ladder 62 shown in FIG. 9. The adhesivefilms 64 are superposed on the straw ladder 62 at both lateral edges.Each straw package 31 is cut from the straw ladder 62, pressed againstthe packaging container 11 and adhered thereto by heat fusion.

To this end, joint portions 33 and 34 (FIG. 4) are formed near bothlongitudinal ends of the first film 14 of the straw package 31, and theunillustrated heaters are pressed against these joint portions 33 and34. As a result, the adhesive films 64 are melted by heat of the heatersand are joined to the resin coated on the surface of the packagingcontainer 11.

In this case, the adhesive film 64 contains, as a base resin, anethylene-vinyl acetate copolymer having a melting point and a vicatsoftening point both higher than those of the hot melt. Accordingly, theadhesive film 64 does not present stickiness at an ordinary temperatureeven after the adhesive film 64 is superposed on the second film 13.Moreover, even when the straw ladder 62 is rolled up, the straw ladder62 does not stick to each other.

Since the ethylene-vinyl acetate copolymer is used only for the secondfilm 13, the consumption of the ethylene-vinyl acetate copolymer can bereduced, resulting in reduced costs. Also, since the straw package 31can be securely adhered to the packaging container 11, the straw package31 does not peel off from the packaging container 11.

Even when the packaging container is stored in an automatic vendingmachine at a temperature of 50° C. or higher, or at a temperature of 10°C. or lower, the straw package 31 does not peel off from the packagingcontainer 11.

In the present embodiment, since the second film 13 and the packagingcontainer 11 can be adhered to each other via the adhesive film 64, bothpolyolefin resins and non-olefin resins can be used for the first andsecond films 14 and 13.

Although the adhesive film 64 can be superposed on the rear surfaces ofthe straw ladder 62 after the straw ladder 62 has been formed, it can bealso superposed on the second film 13 in advance.

When the adhesive film 64 is superposed on the second film 13 inadvance, the second film 13 and the adhesive film 64 are held and heatedby a pair of rollers 67 and 68, as shown in FIG. 10. With thisoperation, the adhesive film 64 can be superposed on the second film 13.The second film 13 is fed from a film roller 70 while the adhesive film64 is fed from an adhesive film roller 69.

Next, the properties of the adhesive film 64 will be described.

In the present embodiment, an ethylene-vinyl acetate copolymer havingthe properties shown in Table 1 was used as a base resin of the adhesivefilm 64.

When melting points and vicat softening points of various kinds ofethylene-vinyl acetate copolymers were plotted, the results obtained areshown in FIG. 11. The vicat softening point is an index for heatresistance.

Ethylene-vinyl acetate copolymers in the area AR1 of FIG. 11 aregenerally used for hot melt. That is, an ethylene-vinyl acetatecopolymer which has an MFR greater than 10 dg/min., which contains vinylacetate in an amount not less than 25 wt. % and which has a meltingpoint of 80° C. or lower and a vicat softening point of 50° C. or loweris used for hot melt.

In contrast, ethylene-vinyl acetate copolymers in the area AR2 of FIG.11 are most preferably used for the adhesive film 64 according to thepresent embodiment, as having been described with reference to Table 1.That is, an ethylene-vinyl acetate copolymer which has an MFR of 0.5-10dg/min (=g/10 min.), which contains vinyl acetate in an amount notgreater than 10 wt. % and which has a melting point of 90°-105° C. and avicat softening point of 70°-85° C. is used for the adhesive film 64.

Also, ethylene-vinyl acetate copolymers in the area AR3 of FIG. 11 maybe used for the adhesive film 64.

In the present embodiment, the adhesive film 64 contains ethylene-vinylacetate copolymer as a base resin. However, in place of ethylene-vinylacetate copolymer, polyolefin resins or copolymers of polyolefin resinsmay be used as a base resin.

Next, a fourth embodiment of the present invention will be described.

FIG. 12 is a lateral cross section of a straw package according to thefourth embodiment of the present invention.

As shown in FIG. 12, a straw package 31 is composed of a first film 14and an adhesive film 71 serving as a second film, and encloses a straw56 in a bulging portion 14a. The adhesive film 71 entirely covers therear surface of the straw package 31.

A plurality of straw packages 31 are formed as an unillustrated strawladder. Each straw package 31 is cut from the straw ladder, pressedagainst the packaging container 11 and adhered thereto by heat fusion.

To this end, joint portions 33 and 34 (FIG. 4) are formed in the flatportions 14b near both longitudinal ends of the straw package 31. Whenthe unillustrated heaters are pressed against the joint portions 33 and34, the resin of the adhesive film 71 is melted at the joint portions 33and 34 and are joined to the resin coated on the surface of thepackaging container 11.

The present invention is not limited to the above-described embodiments.Numerous modifications and variations of the present invention arepossible in light of the spirit of the present invention, and they arenot excluded from the scope of the present invention.
